COMBINED GARBAGE-C'REMA'TORY AND WATER-HEATER.

SPECIFICATION formingpart of Letters Patent No. 639,533, dated December 19, 1899.

Application filed June 9, 1899. Serial No. 719,960 (No modelfl To all whom it may concern.-

Be it known that I, MORGAN JsORAGIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Combined Garbage-Crematory and Water-Heater, of which the following is a specification.

My invention relates. to an improvement in a combined garbage-crematory and waterheater.

The object of my improvement is to provide a cheap way to dispose of garbage by burning same and using the heat generated thereby to heat water. I attain this object by a mechanism described as follows:

The crematory is constructed of common brick or other non-combustible material, firebox lined with fire-brick or other non-conibustible material and having two sets of grates, one set immediately over the other. The lower-grate surface is constructed on the principle of any ordinary rocking and dumpin g grate, and the upper-grate surface is made of hollow tubing, so arranged that the garbage or refuse may be thrown in upon it and all moisture removed from it. As fast as the garbage is dried out it falls on the lower grate and is consumed. A blower using either steam or air is connectedto the upper part of the crematory and so constructed that it will create an artificial draft and carry the vapor up the'chimney Without permitting any odor to escape into the room where the crematory is located. The heating of the water is done in the tubing which forms" the upper-grate surface, the ends of which may be connected to a suitable system for utilizing the hot water obtained.

The invention is clearly shown in the accompanying drawings, in which-- Figure 1 is a front elevation of my device. Fig. 2 is a horizontal section in broken line 2 2 of Fig. 4. Fig. 3 is a similar section in line 3 3 of Fig. 4. Fig. 4. is a vertical section in the broken line 4 4 of Fig. 1, and Fig. 5 is a Vertical section in the broken line 5 5 of Fig. 4.

Referring to the drawings, which show my device in its preferred form, A represents the walls, which may be of brick or other noncombustible material, said walls being built to form a preferably rectangular chamber A, having an opening a in its upper end, in which is secured a smoke-stack B, adapted to carry away the products of combustion and other gases created therein. The lower portion of the chamber A forms the fire-box and is preferably lined with fire-brick or the like. The grate-bars for supporting the fuel are seen at C and are preferably of the class known as dumping grate-bars. They are connected to a hand-lever G by means of bars 0 c c and a link 0 pivoted between its ends to the front wall, as clearly indicated in Fig. 4.

At a suitable distance above the grate-bars O is a second grating D, preferably consisting of a coil of tubing extending across the chamber, as shown in Fig.- 2, one end d of which extends out through the side wall A and is provided with a valve 61. The other end (I is connected to a coil D, which extends along two sides and rear end of the chamber A and terminates in a pipe 62 which passes out through the side wall A and is provided with a valve cl. Inasmuch as garbage contains considerable moisture, the pipe-grating D is placed as near the lower grate-bars as possible, so as to be dried by the fire underneath, without, however, interfering with the combustion. An opening is formed in the front wall immediately below the grating D, through which fuel may be thrown in upon the gratebars 0. The coil D supports the garbage to be consumed, and although the fire heats the water contained in said coil, yet the moist garbage upon the same tends to counteract the effect of the fire. For this reason the vertical coil D is added to the horizontal coil to increase the heating-surface, and as this coil is entirely away from the moist garbage and closer to the fire the water is more effectually heated. The coil D does not, however,extend across the front wall, containing the door opening, but is arranged so as to extend along the two side and rear Walls of the fire-box, whereby said opening is left unobstructed, so that fuel may be readily thrown in upon the grate-bars C. The pipe d is the inlet to the coils D D, and d is the outlet-pipe, through which the hot water escapes, the pipe 61 being placed at the lowest points in the coils and (Z at the highest, so as to allow perfect circulachamber A, a door F with the fire-box A and a door G with the ash-pit A suitable openings being left in the front wall for said doors.

Near the upper end of the chamber A is a pipe H, terminating in an end h, directed upward, the other end of the pipe I-I extending out through the wall A and provided with a valve 71,. The pipe H is adapted to be connected with asuitable blower to create an artificial draft and carry the gases arising therein up through the smoke-stack, and thereby prevent noxious odors and gases from entering the building.

In the use of this device the coils become hot by the action of the fire in the fire-box and the water in said pipes heated. Garbage may now be thrown upon the coil D, the valve h being open to permit the gases being blown up through the smoke-stack. The products of combustion from the fire in passing through this garbage soon remove the moisture therefrom, and the dry portions fall through the coil D upon the fire to be consumed thereby.

In the above I have specifically described my invention in all its details, without, however, intending to limit myself to such exact construction, as various alterations and modifications are possible without departing materially from the invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

A combined garbage-crematory and hotwater heater com prising a fire-box, a garbagechamber, grate-bars in said fire-box, openings leading into said fire-box and garbage-chamber, a horizontal coil of pipe D separating the fire-box from the garbage-chamber and adapted to support garbage and having an end passin g out through the wall of the garbage-chamber, a second coil of pipe connected to the other end-of the horizontal coil and extending into the fire-box in vertical planes along three sides thereof but not across the opening in the front and having its end passing out through the wall of said fire-box.
